Acceptance Testing for ROME

Pete Castle

Test & Quality Manager


  • What is software testing/ Who does it?

  • Why software testing is important

  • Some fundamentals of testing

  • Test Plans & Scripts

  • Sample Testing Techniques

What is software testing
What is software Testing?

  • “Software testing is an empiricaltechnicalinvestigation conducted to provide stakeholders with information about the quality of the product or service under test” Professor Cem Kaner - Director of Florida Tech's Center for Software Testing Education & Research

  • Empirical - derived from experiment, experience, and observation

  • Technical - Having special skill or practical knowledge

  • Investigation - A detailed inquiry or systematic examination

Why testing is important
Why testing is Important

  • All Software has defects (bugs)

  • All software products are ‘prototypes’ (in my view)

  • Software products are getting larger and more complicated - Vista 40% larger than XP @ over 50 million LOC

  • Software Engineering is not as mature as other disciplines e.g. Civil Engineering

  • Software is written by people – people make mistakes

  • Software testing looks to find the most important defects as early as possible – increasing confidence that the software meets specification

Who s involved in testing
Who’s involved in testing?

  • Requirements Analysts – Inspections, Peer Reviews

  • Developers – Code Inspection, Unit Testing

  • Testers – System & Integration Testing

  • Trainers – Training materials production

  • Users – User Acceptance Testing

  • Project Managers – Scheduling, Resourcing, Risks, Issues, Defect Stats

  • Everybody is responsible for quality - NASA

Fundamentals of software testing






Fundamentals of Software Testing

  • Software testing needs planning, tests need specifying, once executed they need results recording, and post completion should be easily auditable

The importance of a planned approach
The importance of a planned approach

  • Important to map out a strategy that will give the greatest level of confidence in the product

  • ‘Ad hoc’ testing may find errors, but may not be cost effective

  • Testing should focus on areas where defects are most likely

  • All testing should have a reason

    • Question “Is a test that doesn’t find an error a good test or not?”

  • Essential to plan what needs to be done and then itemise how it is to be achieved.

Testing mantra
Testing Mantra

  • Mantra - Spiritual conduit, words or vibrations that instil concentration in the devotee.

  • Test as early as possible

  • Gather as much knowledge of the application under test as possible

  • Look for vulnerabilities

  • Build ‘Bug Taxonomies’ (Classification)

  • Use Quicktests (and publicise the fact)

Testing mantra1
Testing Mantra

  • You can always think of another test – but should you?

    • Concept of ‘Good enough Testing’

    • Practicality over dogma

    • Everybody has responsibility for ‘shipping’ the product

  • Record all tests/defects/issues/recommendations

  • Testers are not the sole arbiters of quality

    • Testing only shows problems exist – not their absence

  • Never, ever, ever make it personal

    • Defects are issues with products and process not people

    • Good working relationship is essential for good products

What is a test plan 1
What is a Test Plan - 1

  • Test plan is

    • tool to help plan the testing activity

    • product to inform others of test process

  • Includes

    • Document control

    • Objectives

    • Scope

    • Approach – Schedule, Priorities, Deliverables, Resources, Responsibilities

    • Risks/Contingences

    • Sign-off/Approval

What is a test plan 2
What is a Test Plan - 2

  • Produced by Test Lead/Project Manager

  • Published to Project/Programme

  • Not constrained by format – living document

  • Enough information to be used by anyone to test the product

Rome test plan
Rome Test Plan

  • Ready for review

  • Written by Tim Wells

Test scripts
Test Scripts

  • Test Script - Is a collection of test cases for the software under test (manual or automated)

  • Test Case - A set of inputs, execution preconditions, and expected outcomes developed for a particular objective, such as to exercise a particular program path or to verify compliance with a specific requirement.

Pre conditions information

  • Browsers – IE, Firefox, Safari

  • O/S – Linux, Windows

  • Access Control – Logins, Roles

  • Test Data requirements

  • Date/Time considerations

  • Other document references

Example test script 1
Example Test Script - 1

  • System Test of input of numeric month into data field

Test scripts1
Test Scripts

  • Readable

  • Accessible

  • Usable by anyone – standards

  • Can vary depending upon the type of testing being undertaken

Testing techniques
Testing Techniques

  • Quicktests

  • Negative Testing

  • Integration Testing

Techniques 1 quick tests
Techniques 1- Quick Tests

  • Quicktests - Investigation more important than Confirmation

  • A quicktest is a cheap test that has some value but requires little preparation, knowledge, or time to perform

  • Focus on common coding errors

Techniques 1 quick tests1
Techniques 1- Quick Tests

  • Things that have failed before – Defect data

    • Tab order (particularly when adding new functions)

    • Addresses (BFPO, new Post Codes)

    • Short cut keys

  • Boundaries – Ages, Dates, Values, Increments, Page Breaks

  • Interrupts, Duplications, Ordering of tasks

    • Generate Order before setup – no cost codes, cost centres, suppliers, budgets

    • Exit/Interrupt before completion

  • Consume resource (Dog Piling)

    • Never close a window

    • Never exit an option

Techniques 1 quick tests2
Techniques 1- Quick Tests

  • Force all error messages

    • Informative messages - Spelling

    • Debug information?

  • Capacity/Files – Files to fill all available space, large files, empty files, incorrect format

  • Dependencies – e.g. same student many functions

    • Integration Quicktest

  • Comparisons – screens, data, reports

    • Tools e.g. Beyond Compare, Screen Capture, Redgate Toolset, InCtrl3

Negative testing
Negative Testing

  • Testing the system using negative data – to generate exceptions that cause the software to fail

  • Going against knowledge of ‘How the system should work’

  • For Example - Testing the password where it should be minimum of 8 characters - so test it using 7 and 9 characters

  • Emphasis on breaking not confirmation

Negative testing1
Negative Testing

  • Embedded single quote and other ‘special’ characters e.g. John’s Car, John & Erin, 99%, Straße (German Addresses)

  • Required Data Input – Don’t

  • Field Size – Shoe test (also Quick Test)

  • Field ‘Types’ – Characters in numeric field

  • Boundaries (Upper/Lower) – underage job applications, 101 lines on an order with a maximum of 100 lines

  • Invalid dates e.g. 31/04/08

  • Addresses – BFPO, Hong Kong Addresses, ‘New Post Codes’

  • Web Session Testing – Access web page but not logged in

  • Switch off during upgrade – what happens, does the application know there is a problem?

Integration testing in the large
Integration Testing (In the large)

  • “Testing performed to expose faults in the interfaces and in the interaction between integrated components and products” Sue Myler – Integration Team Lead

  • Usually scenario based rather than low level test cases

  • Relies upon testers having system knowledge & testing expertise – ability to think ‘outside of the box’, develop new tests during testing

  • Relies on successful unit, integration in the small and system testing

  • Can mimic business processes

Integration testing in the large1
Integration Testing (In the large)

Integration Test Cases

  • 3 Applicants

    • 1 applies for 1 post

    • 1 applies for 2 posts - also applies for the same post twice (by accident)

    • 1 applies for 3 posts

    • do their records appear correctly across ROME

  • Delete a Vacancy – what happens to that applicant records?

Integration testing in the large2
Integration Testing (In the large)

  • Short list applicant for post he entered twice, deleting one application

  • Invite for interview but candidate withdraws

  • Candidate then re-applies

  • Data exported, ROME updated, then re-exported, does data appear correctly in target application


  • Software Testing is important for increasing confidence that the software meets specification

  • To get the best results from testing certain fundamentals should be followed

  • Testing is part of software development

  • Different software testing techniques enhance our ability to test

  • Many different types of software testing exist – which we can combine into single test cases/scenarios

Test example data entry screen
Test Example – Data Entry Screen

  • Create Test cases to negatively test (break) the data entry screen
